John. I like Freddie. Honest. I actually like you too. You are usually one of the most helpful guys on the forum, if a bit pedantic. Plus you, unlike Freddie, are fair minded. Plus I'm not making snide remarks to Freddie, just silly ones. That's a clear distinction. If you have a sense of humor. But sorry If I offended you Freddie, ol pal. I was just joshin. But you do tend to scream a bit too loud now and again. And John, you may not believe this but it actually hurt my feelings when you said that I was "no ones pal". I sure hope that's not true. I think I've developed a lot of great relationships with many of the good folks here on the forum. And look forward to maintaining them long into the future. I'm also very grateful for all the help that's available here and yes, I know I get more than I give. Please don't confuse my disagreeing with you with disliking you. Sorry if it's not reciprocated.
I apologize. If I hurt your feelings then I was very mistaken and very wrong.

Does all this mean the 64bit Sonar doesn't ROCK? (and John, before you go and tell me that this isn't the Coffee House, I'd like you to take the new headmaster's paddle that you got this Christmas, and put it up one of your favorite places...)

Yorolpal this is not the Coffee House. The crude remarks don't go over well here.
WOW! John ... you need to lighten up a bit mate! Just to assure you Yorolpal at least one person here was not offended, even slightly, by your posts.

Hmm, at 32 bits SONAR needs N megabytes of RAM. At 64 bits, SONAR needs N * 2 megabytes! Holy crap! Math strikes again!
Sorry, Freddie. SONAR may indeed have a memory leak, and it may only happen with 64-bit data. That's certainly not impossible. Memory leaks are very easy to have in a memory-intensive application such as SONAR.
However, it might be prudent to confirm that conclusion prior to announcing the discovery of a new bug in 20-point bold red text.
lol
Someone said: I've had more time to play with this, and am withdrawing the bug remarks.
This appears to work as designed and is actually a pretty cool feature.

You also get 64 bit wave files if you:
- Set record bit depth to 64 bit.
- Set render bit depth to 64 bit.
- Set import bit depth to 64 bit.
I'm assuming that was what Freddie was referring to.
(“Global Options”---> “Audio Data” )
It's a pity his post was so hysterical and over the top.
It's gonna confuse a lot of people into thinking the 64 bit version
of SONAR has a memory leak.
Exactly! Sorry that it sounded hysterical. Not my point at all. The workaraound is just use 32bit floting files instead until Cakewalk fix this. No big deal. Regards Freddie

Let see people often post what they think are bugs. Sometimes they are wrong. Sometimes they are right. Where is Yorolpal when they post. Why is it OK to make snide remarks to a person that has never attack anyone on this forum? One that has tried to be open and helpful to everyone. Yorolpal is no ones pal.
Thanks John. Can some please try this?
1. Make a 64bit clip inside SONAR. 2. Check SONAR in your system with help of CTRL + ALT+ Delete. ----> Check SONAR program. 3. Hit play and you will see SONAR reads / eat some Memory space when it plays the 64bit clip. 4. That's total correct when SONAR plays a new clip for the first time. SONAR read the clip into the memory space because it isn't present in the memory space yet. 5. Hit STOP! 6. Hit play again to play the same 64bit clip in SONAR. ---> CTRL + ALT+ Delete. ----> Check SONAR program. 7. Now the clip should be read from the RAM memory space only but instead SONAR continue to read /eats / buffer into the memory space? 8. As you can see now, everytime SONAR play's that 64bit clip you will see it continue to eat /reads it into the memory always. = SONAR eats memory space everytime SONAR plays that or any other 64bit AUDIO files in your project.- (As an exampel so you clearly understand the problem. IF Your computer have example 8GB RAM. If the 64bit CLIP used 1GB RAM everytime you plays it in SONAR, you can only play the song 8 times. After that all RAM MEMORY would be gone eaten up by SONAR) 9. If you use 32bit file format or else in the same project you will see, that it work normal everytime SONAR plays those 32bit clips. Reads it one time into Memory Space, then later on reads all those clips from the RAM memory only. = No leak! Regards Freddie

To make one thing Straight! Its overkill 64bit files in normal use, alright! Still it should work to work with 64bit audiofiles in SONAR. I have just used it because I can, I have space on my harddrive too. I can easliy use 32bit floaing files instead, no problem... Regards Freddie

dont kiss john ass now i injoy alittle joking in my studio as long as it not to personal iv made some rude remarks to freedie ala mister 64 himself. but ill admit he has more knowlege than me
its all in god humor.if you cant take the heat get your thin skin out of the forum.
you would think that musicans and producers would be use to critics
yoropal ill still be your pal even if your forum pic looks like radiation poisoning
but unfortunatly john's right and if i was less sarcastic id be getting some answers on my post. i still try to think i have alittle love in here.where all in the same sonar boat.some just have bigger boats.

This thread has me confused. If a project has 64bit files playing back (if possible), wouldn't one have to be using an audio interface that supports the playback or recording of a 64bit file?
I mean my audio interface only supports from 16 bit- 24bit (i'm sure).
I'm just a hobbyist with this music production stuff, so can somebody enlighten me?

Hello all,
I tested 64 bit files with my system and I could not produce Freddie's memory leak. Test project contained 26 stereo tracks (64bit wave files, size of each 6,35 MB).

the 128-bit version of Sonar 9.0 fixes this!
But seriously, I don't think sonar "reads the contents of the clip into memory" and then the second play is from RAM. I'm pretty sure you're streaming from disk all the time (hardware buffering aside)

Thomasabarnes - you can render files at bit depths higher than your interface can handle in the box. The tracks are then dithered down to the appropriate bit depth handleable by your interface or truncated to that depth by the interface driver at play back. A reason to do this is the multiple internal bounces you may perform will occur with higher precision at the higher bit depth. This can be important because when bouncing you are rarely maximized to the loudest peak. “If all 16 bits in a 16-bit recording are used then the result is only inadequate if, in an anechoic chamber with 0 dB SPL of room noise, the recording is to be played back at greater than 96dB SPL, peak amplitude.” (Aldrich, 2005, 350). Now, this presumes a great stereo, but you get the point... for playback, 64 bit 192 would be massively more information than required to reproduce every bit of sound any human can hear. “Many inexpensive converters will demonstrate a marked improvement when comparing 44.1 kS/s recordings with 96 kS/s recordings, for example. This is often because the filters in the converters are not of audibly transparent quality.” (Aldrich, 2005, p346). Freddie H - have you considered plug ins? Is it possible that one of the plugs you are using when testing is causing the issue? Even something like the x64 EQ might be the issue. John - I appreciated your info on the w64 file format, and I understand that this file format has to do with the file system and not the bit depth of the audio stored in the file. So, for example, a 16 bit 44.1 kS/s recording will have a files size approximately identical in the wav or the w64 file formats. The advantage of the w64 file format is the tremndous file size possible. Nika Aldrich. Digital Audio Explained for the Audio Engineer. 2005.

Why do I have time for this?
I tried last night and gave up. I did get far enough to suspect the outcome you've arrived at. I just didn't have the headspace to record/annotate all my findings. So I commend your effort. Much appreciated. 5 thumbs!
